We currently have targets for bare-metal Armv7-R, Armv7-A and Armv8-R, but only in Arm mode. This PR adds five new targets enabling bare-metal support on these architectures in Thumb mode.

This has been tested using https://github.com/rust-embedded/aarch32/compare/main...thejpster:aarch32:support-thumb-mode-v7-v8?expand=1 and they all seem to work as expected.

However, I wasn't sure what to do with the maintainer lists as these are five new targets, but they share the docs page with the existing Arm versions. I can ask the Embedded Devices WG Arm Team about taking on these ones too, but whether Arm themselves want to take them on I guess is a bigger question.
